摘　　要：分布式雷达恒虚警处理(Constant False Alarm Rate,CFAR)检测信息融合技术是雷达探测领域的重点。融合中心采取的融合方法作为分布式恒虚警系统的核心,需要根据实际条件合理地选取不同的融合方法。首先对CFAR检测系统进行介绍,之后在融合中心分别采取两种不同融合算法的条件下,研究了分布式CFAR检测系统在韦布尔噪声背景下的检测概率。通过仿真实验分析了不同融合算法对系统的影响。Distributed CFAR detection information fusion technology is the focus of radar detection.The fusion method adopt⁃ed by the fusion center is the core of the distributed CFAR system,and different fusion need to be reasonably selected according to actual conditions.The paper first introduces the CFAR detection system.Then,under the conditions of adopting two different fusion algorithms in the fusion center,the detection probability of the distributed CFAR detection system under weibull moise background is studied.Finally,all the above studies are simulated and analyzed and different algorithms are compared.
